I've been having some initial success modelling in Sketchup and uploading to Shapeways. However, as I become a little more adventurous, a few errors have crept in and some uploads have been unsuccessful. This has led me to export the *.dae file to Meshlab, thus converting the file to *.STL.This then leads me to open the STL file in Netfabb Basic so that I can effect the necessary repairs. The problem that I'm having is that I don't seem to be able to save or export the resulting repaired file in anything other than a *.fabbproject file - which Shapeways doesn't recognise as a legitimate type for uploading.
Surely there's a simple solution to this without investing in Netfabb Professional at what for me is a prohibitive cost?
